The urgency of transportation organization improvement in the system of agricultural products delivery to the country’s population under conditions of import substitution is substantiated here. The article proposes to use the logistic approach. The advantage of the approach is that it combines and considers the processes of harvesting, transportation and distribution of goods in reciprocal relationship; and on this basis the concept of united harvesting, transportation and distribution complex (HTS) is introduced. The main organizational schemes for agricultural products delivery from the producer to the places of consumption are considered. Mathematical formulation of the vegetables transportation system optimization at HTS complex is performed based on the inclusion of receiving and classification units (RCU) in the logistics chains of delivery from the producer to the places of agricultural products consumption. An optimized multi-factor economic and mathematical model is proposed. It allows to identify RCU rational locations and their capacity, to calculate the number of road transport vehicles necessary to deliver vegetable cargo in full, provided that the recipients are optimally assigned to the product suppliers and available vehicles are optimally distributed for all modes of transport. Methods of the process main characteristics calculation are described.

A globalização aprofundou suas estratégias capazes de fomentar a competição global e de definir os agentes hegemónicos dessa corrida, que de um lado estão grandes corporações em concorrência e de outro os trabalhadores em uma luta de classes, sendo os atributos expressos a esse globaritarismo os responsáveis pelo (re) ordenamento do território, impactando na política, economia e cultura da sociedade. Portanto, a problemática apresentada tem servido como referência para a importância de analisar o conceito de logística sob o olhar geográfico e empresarial, compreendendo asua atuação e limitações a partir de procedimentos metodológicos que abrange desde levantamento bibliográfico sobre a temática até o mapeamento das condições atuais do sistema de transportes de cargas na cidade.ABSTRACT Globalization has deepened its strategies to foster global competition and to set its hegemonic agents having, on one side, large corporations in competition and, on the other side, workers on a class struggle, where the attributes in this globalization process are the ones responsible for spatial planning of cities, thus impacting politics, economy, and culture of the society. Therefore, the problems stated have served as a significant reference to analyze the concept of logistics from a geographic and business perspective by understanding their role and limitations from methodological procedures that range from literature on the subject to the mapping of current conditions of the cargo transportation system in the city.

This paper aims to analyze the classical transport system using only two processing centers, maintenance can ensure, without negatively impacting the transportation system optimization. To achieve transport system simulation packages have been used to simulate Petri and implementation specialist and preparing conclusion is made based on data specialist. The model is intended to be a source of help in the activities of companies seeking to optimize the transport system and not be disrupted by achieving maintenance. Benefits are those prototypes and analyze the whole system after the implementation of tracking and being able to control the entire system, leading to the prevention and elimination of queues later appearance possible accidents. Studying this system model can deduce new information without the high costs.

Multiple-Criteria Analysis and Choice of Transportation Alternatives in Multimodal Freight Transport System In the paper the multimodal freight transportation system with a finite number of known alternatives, defined by the routes and modes, is considered. The objective of research is to suggest the approach for evaluation and choice the alternatives of cargo transportation. The following main tasks are considered: choice of indices characterizing efficiency of multimodal transportations, formation of optimization criteria of the multimodal freight transportation, construction of the model of the multimodal transportation system, calculation the performance criteria of cargo transportation. The study presents the Analytic Hierarchy Process (AHP) as the most suitable approach for comparative evaluation of different routes and modes of cargo transportation.

This article provides an overview of dynamic models of the organization of railway freight transportation, in which the cargo flow is formed on the basis of the interaction of neighboring stations. Several configurations of a section of the railway network are considered and two approaches to the organization of the cargo transportation process are proposed, depending on the demand for them.
